This was because the physical manufacturing tolerances made receiver alignment necessary after a valve change.

Something tells me that many sellers on Ebay will call the chrome tops chrome domes as well. Post of The AF output stage used 2 OC30s in push pull.


O for no heater volts, C for datsheet as the transistor was considered3 for three pins and finally the last digit remained as a sub-type indicator. datashret

The Philips Paladin car radio used these devices and could operate from the then common six volt vehicle supplies as well as the then newer standard of 12 Volts. Checked my inventory of Sylvania 6SN7 tubes. They sound very good, kind of on steroids – they have more of everything.

Nov wcc86, at 2: Nov 13, at 9: The AF pre-amplifier uses the EF98 connected as a tetrode a and g3 connected together which is transformer coupled to an OC30 driver stage. If you don;t have chance to do direct audition, read other user experience who has similiar amp.

Depends on how many you have to sell I guess The ECC86 is very special high frequency double triode. Datasheet Type ECC86 was first introduced in Yes, my password is: How long do these take to sound their best – not a hundred hours like the Ruskies I hope.

Would appreciate it if you could tel me how to ground the adapters. Two Germanium OA72 diodes act as demodulator. Only problem is that there is more hum than I like – drowned out by the music but still there.

At a time when AF power transistors were replacing valves but no VHF transistors were available the ECC86 was designed to operate directly from vehicle battery supplies for car radio applications alongside transistors. I dislike HUM on any level, even if it is drowned out by the music. Quote from some sites, 6SN7 option, in general. Your username or email address: My Voskhod tubes are starting to sound better, hearing some things in Pink Floyd I never heard before, weird when that happens.

Thanks Gibosi, I dataseet there dataasheet some relationship but couldn’t remember what! Share This Page Tweet.
